What are the causes of tympanic membrane perforation?


1. Inflammation

2. Perforation causes hearing loss: the sound first vibrates the tympanic membrane, and then travels to the cochlea through the middle ear ossicular chain, which causes neural reflexes to form hearing. After the tympanic membrane is perforated, the effective vibration area of ​​the tympanic membrane is reduced, and the energy of external sound waves into the inner ear is weakened and appears. Hearing loss.
